The Labmart Type B1 Macro Fluorescence Cuvette is a precision optical cuvette designed for fluorescence and fluorometric measurements. It features four optically polished windows, fire-fused construction, precise optical geometry, and chemical-resistant construction for reliable laboratory analysis. Available in optical glass, Pyrex glass, UV quartz, and IR quartz configurations.

Product Overview

The Type B1 Macro Fluorescence Cuvette is designed for fluorescence spectroscopy where optical access through multiple faces is important for excitation and emission measurements. Unlike conventional two-window spectrophotometer cuvettes, the B1 configuration provides four polished optical windows and a polished base.

The cell is manufactured using fire-flame or thermal-fusing techniques, eliminating the need for glued or fritted side assembly. This creates a robust, integrated construction with highly transparent fused sides.

Precision optical-path alignment maintains the light-path tolerance within ±0.1 mm, while the fused construction provides good integrity and helps prevent leakage and cross-contamination.
